Template creation (Pathfinder)

[wdmartin]

Hi, first post here, so I hope this is in the right subforum.

I'm working on adding a homebrew template for use in a game I'm GM'ing. Here's the template:

A Sinwarped Creature has been twisted and corrupted by exposure to a particular school of Thassilonian sin magic.

Prerequisites: The Sinwarped Creature template may only be applied to creatures of the animal or fey type.

Subtype: gains the [augmented] subtype.

Alignment: changes to Evil.

Spell-Like Abilities: a Sinwarped creature gains spell-like abilities based on its hit dice and the school of magic to which it was exposed.

Sinwarped Creature (Prideful)
universal at will - Ghost Sound
hd 1-2 one of Color Spray, Silent Image or Ventriloquism; 3/day
hd 3-4 one of Invisibility or Minor Image; 3/day
hd 5-6 one of Displacement or Major Image; 2/day
hd 7-8 one of Greater Invisibility or Phantasmal Killer; 2/day
hd 9-10 Mirage Arcana; 1/day
hd 11+ Permanent Image; 1/day

All of these spell like abilities function with a caster level equal to the
base creature's hit dice. Save DCs are governed by the base creature's CHA.

I've omitted the spell-like ability lists for the other six sins in the interests of brevity.

I studied the implementation of the Fey Creature template, and I think most of this is fairly straightforward, though I'm planning on implementing seven different templates rather than one large template for all seven sins. But there are two kinks I'm having trouble working out.

1) How do I make the template apply only to animals OR fey? It looks like the Pre-reqs dialog is additive -- so I could set that to apply rules require both animal AND fey. But I need OR. I've tried using the Expr-reqs dialog with expressions like this:

#hastype[tpAnimal]|#hastype[tpFey] <> 0

#hastype[tpAnimal] <> 0|#hastype[tpFey] <> 0

But the compiler doesn't like that. Apparently boolean operators aren't allowed there. So ... how do I do an OR in a type pre-requisite?

2) The spell-like abilities gained at hit dice 1, 3, 5, and 7 involve a choice of spells. If it were just a single spell that every creature with the template gets, that'd be simple to set up. But I have no idea even how to begin putting a selection in there. Suggestions?

Thanks.
